Applications of Hydro-Chemical and Isotopic Tools to Improve Definitions of Groundwater Catchment Zones in a Karstic Aquifer: A Case Study

Some researchers have proposed the groundwater protection zone (GPZ) method as a methodological framework for defining safeguard zones of groundwater bodies. Its goal is to protect the quality of water intended for human consumption and to facilitate a common implementation of this method in all European Union member states. One of the criteria used to establish GPZs is to define contributing catchment areas (CCAs). This methodology has been applied to the Sierra de Cañete, a region comprising a carbonate aquifer in the province of Malaga, Spain. The tools used to define CCAs are hydro-chemical and isotopic characterizations, namely water isotopes (i.e., 2H, 18O and tritium) and the isotopes of dissolved sulfates (i.e., 34S and 18O). Traditionally, the Sierra de Cañete aquifer has been divided into six sectors. Hydro-chemical and isotopic characterization differentiated between two large areas in the carbonate aquifer. The southern part presents younger water that is the result of faster recharge and that shows a high level of karstification, while the northern area has a slower flow, and recharge is produced over several years. In addition, the northern part is hydraulically connected to an alluvial aquifer (i.e., Llanos de Almargen) that borders the Sierra de Cañete to the north. This aquifer has high levels of pollution due to agricultural and livestock activities carried out in the Llanos de Almargen area. This pollution is transmitted to the carbonate aquifer when groundwater depletion occurs. Therefore

Effect of implantoplasty on the elastic limit of dental implants of different diameters

Background Implantoplasty reduces both implant diameter and the thickness of its walls, subsequently reducing the ability of the implant to resist fracture in response to functional load. In combination with an increase in the crown-implant ratio due to bone loss, this could increase the lever effect, which in presence of high masticatory forces or parafunctional habits, could lead to complications such as fracture of the implant or loosening of the prosthetic screw. Objectives To determine the elastic limits of internal connection, dental implants of different designs and diameters after an implantoplasty. Materials and methods This in vitro study included 315 tapered internal connection titanium dental implants, the threads of which were removed with an industrial milling machine-for standardized implantoplasty (IMP1; n = 105)-or with the conventional approach-manually, using high-speed burs (IMP2; n = 105). The remaining 105 implants were used as controls. The final implant diameters were recorded. The quality of the newly polished surfaces was assessed by scanning electron microscopy. All implants were subjected to a mechanical pressure resistance test. A Tukey''s test for multiple comparisons was used to detect differences in the elastic limit and final implant diameters between the implant groups. Results There were statistically significant differences in the elastic limit between the IMP1, IMP2, and control groups (p < 0.05). Furthermore, the implant diameter was significantly smaller in the IMP1 and IMP2 groups (p < 0.05). Scanning electron microscopy revealed smooth implant surfaces in the IMP1 and IMP2 groups, with some titanium particles visible in the IMP1 group. Conclusions Implantoplasty significantly decreased the elastic limit of internal connection titanium dental implants, especially in those with a smaller diameter (3-3.5 mm)

Chemical composition of landfill leachate in a karst area with a Mediterranean climate

Abstract Between March 1994 and April 1997, the physical and chemical parameters and chemical composition of the urban solid waste leachate of the Marbella landfill (southern Spain) were determined. The data obtained show an ammonium and sodium chloride and bicarbonate type, a pH 1 7 and high mineralization, effectively described by the following parameters: Na , Cl -and alkalinity. The chemical composition depends on the rainfall: in dry years, the mineralization and component concentrations have values as much as double those found in normal rainfall years. After storm events, a major and rapid dilution (within several hours) is seen in the leachate

La lengua artificial nadsat de 'A Clockwork orange' como problema de traducción

Anthony Burgess es el autor de A Clockwork Orange, una novela experimental en la que utiliza el lenguaje para demostrar lo fácil que es cambiar la opinión de la gente y, en concreto, del lector del libro. En este caso, lo hace mediante una lengua artificial creada por él mismo que recibe el nombre de nadsat y cuyo origen está estrechamente relacionado con el idioma ruso y la fusión del comunismo y el capitalismo. A través de este argot, el lector es víctima de un lavado de cerebro que permite que se sumerja en el violento mundo que relata el protagonista y que no perciba la gravedad de los terribles delitos que este comete. Mientras que el objetivo del autor se cumple en el libro original, la traducción al español no produce el mismo efecto. Por ello, este trabajo pretende analizar la traducción del nadsat al español, compararla con el texto original para determinar si el traductor supo resolver el problema de traducción que implica el uso de esta lengua artificial y proponer una traducción de algunos fragmentos de la novela que se ajuste a la situación comunicativa originalAnthony Burgess es l'autor de A Clockwork Orange, una novel·la experimental on utilitza el llenguatge per a demostrar com és de fàcil canviar la opinió de la gent i, en concret, del lector del llibre. En aquest cas, ho fa mitjançant una llengua artificial que ell mateix ha creat que s'anomena nadsat i l'origen de la qual està fortament relacionat amb l'idioma rus i la fusió del comunisme i el capitalisme. A través d'aquest argot, el lector es víctima d'un rentat de cervell que permet que es submergeixi en el violent món que descriu el protagonista i que no percebi la gravetat dels terribles delictes que comet. Mentre que l'objectiu de l'autor es compleix en el llibre original, la traducció a l'espanyol no produeix el mateix efecte. Per això mateix, aquest treball pretén analitzar la traducció del nadsat a l'espanyol, comparar-la amb el text original per a determinar si el traductor va saber resoldre el problema de traducció que implica l'ús d'aquesta llengua artificial i proposar una traducció d'alguns fragments de la novel·la que s'ajusti a la situació comunicativa originalAnthony Burgess is the author of A Clockwork Orange, an experimental novel in which he uses the language to show how easy it is to change people's opinion and specifically reader's opinion. In this case, it is realized by the use of an artificial language created by himself called nadsat which origin is closely related to the Russian language and the fusion of communism and capitalism. Through this argot, the reader is brainwashed, what lets him immerse in the violent world that describes the protagonist and avoids him from noticing the seriousness of the terrible crimes he commits. While the author's target is fulfilled in the original book, the Spanish translation does not have the same effect. Thus, this academic work wants to analyze the Spanish translation of the nadsat, compare it to the original text to figure out if the translator could solve the translation problem caused by the use of this artificial language and suggest a translation of some extracts of the novel that fits the original communicative situatio

Two heads are better than one, but how much? Evidence that people's use of causal integration rules does not always conform to normative standards.

Many theories of causal learning and causal induction differ in their assumptions about how people combine the causal impact of several causes presented in compound. Some theories propose that when several causes are present, their joint causal impact is equal to the linear sum of the individual impact of each cause. However, some recent theories propose that the causal impact of several causes needs to be combined by means of a noisy-OR integration rule. In other words, the probability of the effect given several causes would be equal to the sum of the probability of the effect given each cause in isolation minus the overlap between those probabilities. In the present series of experiments, participants were given information about the causal impact of several causes and then they were asked what compounds of those causes they would prefer to use if they wanted to produce the effect. The results of these experiments suggest that participants actually use a variety of strategies, including not only the linear and the noisy-OR integration rules, but also averaging the impact of several causes

Cuerpos impúdicos. Instagram y feminismo

Premi UAB de l'Observatori per a la Igualtat als millors Treballs de Fi de Grau amb perspectiva de gènere. 5a Edició, curs 2019-2020Entre los selfies de Instagram se atisban identidades. Y con ellas descubrimos que, de hecho, la aplicación ofrece un espacio para que el subalterno exprese su voz. Observamos una nueva estrategia feminista: publicarse parcial o totalmente desnudas para empoderarse. Pero, ¿es eso posible, partiendo de las mismas herramientas que el patriarcado usa para cosificar los cuerpos femeninos? Esta investigación explora la diferencia que supone que la mujer controle el discurso desde el que se representa su cuerpo; y que lo haga, además, en una red social como Instagram y desde una consciencia manifiestamente feminista.Entre els selfies d'Instagram s'entreveuen identitats.
